My girlfriend was born March 17 1996 and i was born november 29 1996 are we a good match?

Yes, you are a good match. You can be honest and open your heart to each other. Both of you wil rely on the other and the family life. But you may face one problem. You may not have much private room for the each other, because you know the other pretty well. So it is suggested to leave some space for the other.
